PURPOSE: A micro type optical projector system of projection module is provided to reduce manufacturing costs by satisfying stable design performance and mass production. CONSTITUTION: A micro type optical projector system of projection module comprises a surface light source lens, collimation lenses(220,230), and a lens(240) for projector. The illumination system is designed so that the light, coming out in the light source, has the uniform brightness. The collimation lens converts the uniform surface light source which is formed with a surface light source lens into the parallel light source. The lens for projector is designed in order to have the uniform and collimated light by the surface light source lens and collimation lens cope with each field main light incident angle of a projection system. The panel and projection system are composed in order to cope with the illumination system. |
